Melissa takes the bottle of water, but doesn't open it yet- she hasn't quite adjusted to the fact that she's not currently a vampire. Mostly because thinking about it too hard triggers an existential crisis that she was not expecting and if Melissa is good at anything, it's ignoring potential moral quandaries.

"Melissa," she says, with a nod of thanks as she lifts up the bottle, "I will say, I do think this is worse than security guard training. ...Though we may need to go back and talk about that 'other world' comment, because holy shit did you run through that way too casually."
